Quinoa requires abbreviate daylengths and air-conditioned temperatures for
acceptable growth. Areas in South America area it is still produced tend to be
bordering agronomical areas that are decumbent to aridity and accept soils with
low fertility. Cultivated quinoa will annual and aftermath berry at top
elevations amid 7,000 and 10,000 ft in Colorado back it requires a
air-conditioned temperature for acceptable abundant growth. Research conducted
in Colorado appear that temperatures which exceeded 95°F tended to could cause bulb cessation
or pollen sterility. In several years of trials abreast the Twin Cities,
Minnesota, quinoa plants accept bootless to set seed; apparently due to top
temperatures.
Quinoa plants are usually advanced to ablaze frosts (30° to 32°F).
Plants should not be apparent to temperatures beneath 28°F to abstain the 70 to 80% accident that occurred in Colorado during
1985 if plants were in mid-bloom (Johnson and Croissant, 1990). However, plants
are not afflicted by temperatures down to 20°F
afterwards the atom has accomplished the soft-dough stage. Quinoa will annual
beforehand if developed in areas with beneath daylengths.
Quinoa is about not a broadly acclimatized crop due to temperature
sensitivity. Farmers should agreement aboriginal afore burying ample acreages.
